Abstract: By selecting an experiment plot from the fine forest experiment station in Jimusaer County of Xinjiang Uygur Autonomous Region,where the site conditions,way of inoculation Cistanche deserticola age of host sapling,planting sapling density were well selected all analogous in the fine tree seeds production base of Cistanche deserticola,we have studied the effect of different excavation hole treatments on soil moisture content around Haloxylon ammodendron rhizosphere. The results showed that the excavation hole resulted from Cistanche deserticola excavation had significant effect on the soil moisture content, with an influence range differing in soil layers. At the level of 0NFA4820 cm surface soil, the effect was most significant. The soil closer to the excavation hole had less moisture content. In the soil layer of more than 20 cm below the ground, this changing trend still existed. However, locations of more than 45 cm apart from the excavation hole, the influence of excavation hole on soil moisture content became less. The soil moisture content of different Cistanche deserticola excavation hole treatments existed significant differences. In the soil layer of 0NFA4810 cm, the ranking of soil moisture content in descending order was as follows: the control group backfill excavation hole side inner backfill excavation hole non-backfill excavation hole side. In the soil layer of 10NFA4830 cm, the ranking of soil moisture content in descending order was as follows: backfill excavation hole side the control group inner backfill excavation hole non-backfill excavation hole side. In the soil layer of 30NFA4850 cm,the ranking of soil moisture content in descending order was as follows: the control group inner backfill excavation hole backfill excavation hole side non-backfill excavation hole side. The main reason for a low water moisture content in non-backfill excavation hole was that excavation increased the evaporation profile and exposure of deep layer soil to atmosphere, making a continuous evaporation of soil moisture content in the excavation hole sides. Backfill excavation hole could put off or prevent the pervasion of the moisture content from the excavation hole side to atmosphere. However, due to the fact that the backfill soil structure changed, therefore, the backfill soil moisture content changed as time changed, which was quite different from the changing rules in the control group, backfill excavation hole side and non-backfill excavation hole side.
